Definitions

  • the present invention relates to a cornering light module for a motor vehicle headlight according to the preamble of claim 1.
  • Such a cornering light module is from the EP 1 920 972 A2 respectively.
  • Such cornering light modules are used to align the motor vehicle headlight, which is oriented parallel to the longitudinal axis of the motor vehicle when driving straight ahead, to the inside of the curve to better illuminate the curved roadway ahead of the motor vehicle when cornering.
  • a complex light source is understood to mean that part of the cornering light module which is pivoted as a structural unit to fulfill the cornering light function.
  • a complex light source contains in particular the actual light source, be it a semiconductor light source, an incandescent lamp, a gas discharge lamp or another light source, and an optical system which generates the desired light distribution in front of the headlight from the light of the light source.
  • the swiveling parts of other known cornering light modules are stored in a rigid bearing geometry in the swivel frame.
  • the storage takes place, for example, in that bearing pins rigidly connected to the complex light source and ideally aligned along the swivel axis are mounted in plain bearing bushes rigidly connected to the swivel frame and ideally aligned.
  • the object of the invention is to reduce the increased frictional resistance caused by misalignment and to cover the entire bearing play required for a desired low friction To guarantee temperature range, in particular also in the range of low temperatures.
  • the invention is initially based on the knowledge that the increased friction is often caused by non-aligned bearings of the complex light source in the swivel frame.
  • the non-aligned bearings occur in particular, but not only, with pivoting frames and / or support elements of the complex light source, which at least partially consist of plastic and are produced by an injection molding process. When the injection molded parts cool, there is a delay that cannot be avoided with reasonable effort, which often leads to the bearings not being exactly aligned.
  • non-aligned bearings lead in particular to the fact that the complex light source and the swivel frame are braced against one another when they are joined together. As a result, the bearing pins then sit crookedly in the rigid slide bearing sleeves. The bracing forces are supported in the bearings. Due to the misalignment of the bearing pins in the plain bearing sleeves, the bearings then only bear on a fraction of their otherwise available storage area, which in some areas leads to greatly increased values of the surface pressure (effective force per unit area). In conjunction with the intended swivel movements, the increased surface pressure in the prior art leads to increased friction and increased wear as a result of increased friction.
  • the object of the invention is to provide a cornering light module which does not have the disadvantages described, or at least only to a reduced extent. This object is achieved with the features of claim 1.
  • the cornering light module according to the invention is characterized in that at least one of the two bearings has a spherical bearing with a spherical-spherical bearing shell, a ball and a bearing pin.
  • the spherical bearing has the great advantage that the spherical symmetry of the bearing surfaces, which are formed by the inner side of the spherical spherical bearing shell and the outer side of the spherical ball in the spherical bearing, a change in the position of the ball in the bearing shell and thus an adjustment of the angular position of the receptacle of the associated bearing pin in the ball to an inclination of the associated bearing pin allowed.
  • the ball only has to rotate a little in its spherical cap-shaped bearing shell.
  • the ball has a central recess which serves as a slide bearing sleeve in which the first bearing pin is rotatably mounted.
  • the storage therefore comprises two interrelated individual supports. From the inside out, these are first a slide bearing of the bearing pin in the central, preferably cylindrical recess of the ball and then, further out, a slide bearing of the ball in the spherical bearing shell.
  • Figure 1 shows the technical environment of the invention.

  • the carrier element 22 also has a holding frame 22b which is rigidly connected to the heat sink 22a.
  • the invention is not restricted to use in connection with semiconductor light sources and can also be used with other light sources, in particular incandescent lamps or gas discharge lamps.

  • the first axis 34 will therefore generally be aligned parallel to a vertical axis of the motor vehicle when the cornering light module 14 is used as intended. This corresponds to the z direction indicated in the figures.
  • the x direction lies parallel to a longitudinal axis of the vehicle and the y direction lies parallel to a vertical axis of the vehicle.

  • the swivel frame 28 with the cornering light module 14 can additionally be pivoted in the housing 12 about a second axis 36 orthogonal to the first axis 34 and transverse to a light emission direction essentially parallel to the x direction.
  • the second axis 36 will therefore generally be oriented parallel to a transverse axis of the motor vehicle, that is to say parallel to the y direction.
  • the pivotability of the cornering light module 14 around the second axis 36 allows the headlight range to be regulated.

  • a non-alignment means that an imaginary center line through the first bearing pin 56 does not match an imaginary center line coincides with the second bearing pin 60, but that these center lines enclose an angle with one another or run parallel to one another or are skewed with respect to one another.
  • Figure 3 shows a section through a cornering light module 100 whose position corresponds to the section shown in FIG Fig. 2 is shown. Unlike that Figure 2 is in the Fig. 3 not a complete longitudinal section through a cornering light module. Figure 3 Rather, it shows the section only in the area of the first bearing 30 and the second bearing 32. The illustration in FIG Figure 3 shows in particular differences to the subject of Figure 2 , which result from the respective type of mounting of the complex light source 26 in the swivel frame 28.

  • the cornering light module 100 has an advantageous realization of the bearing. This is characterized in that at least one of the two bearings 30, 32 is a spherical bearing with a spherical cap-shaped bearing shell, a ball and one Bearing pin.
  • the ball has a central recess, which serves as a slide bearing sleeve, in which the first bearing pin 68 is rotatably mounted.
  • the storage therefore comprises a total of two related individual bearings. From the inside out, these are first a slide bearing of the bearing pin in the central, preferably cylindrical recess of the ball and then, further out, a slide bearing of the ball in the spherical bearing shell.
  • the central recess in the ball 66 forms a plain bearing sleeve for the first bearing pin 68.
  • the central recess and the first bearing pin 68 are matched to one another to form a plain bearing.

If the ball bearing 70 is part of the swivel frame 28, then the associated second bearing pin 72 is part of the complex light source 26. This corresponds to the embodiment shown. On the other hand, if the ball bearing 70 is a component of the complex light source 26, then the associated second bearing pin 72 is a component of the swivel frame 26.

  • the spherical bearing allows in particular a skewing of the associated bearing pin, here the first bearing pin 68.
  • Axial misalignment between the first bearing 30 and the second bearing 32 in any case lead to a tensioned seat of the bearing pins 68, 72 in their receptacles, be it the reception in the ball of the spherical bearing or the reception in the inner ring of the ball bearing 70.
  • This tensioned seat leads inevitably to an, albeit slight, inclination of the bearing pins 68, 72 relative to one another. Since the spherical bearing allows such an inclined position without problems, there are, as was explained in detail above, no such high surface pressure values between the bearing surfaces as would be the case without an inclined position-tolerant bearing. A For example, misalignment is not tolerated in the Fig. 2 shown. Due to the lower surface pressure values in the invention, the invention also allows improved maintenance of a minimal bearing clearance at low temperatures.
  • the spherical bearing for one of the two bearings, in particular for the upper bearing, the effects of unavoidable distortion between the swivel frame 28 and the holding frame 22b of the complex light source 26 on the resulting surface pressures in the bearings are reduced.

  • the bearing shell 64 is preferred Design fastened by screwing into the swivel frame 28 and for this purpose has an external thread that fits an internal thread in a recess in the swivel frame 28 that is designed to receive the bearing shell 64.
  • the Figure 4 shows a cross section through an embodiment of a cornering light module according to the invention to explain embodiments of the invention.
  • the light source 20 is a semiconductor light source and it is thermally coupled to the heat sink 22a of the carrier element 22.
  • the carrier element 22 preferably has a blower 42 with a blower housing, which actively generates an air stream 44 that dissipates heat from the semiconductor light source 20.
  • the cooling air is drawn in by the fan 42 from a direction perpendicular to the plane of the drawing.
  • the semiconductor light source 20 is therefore attached to the compact and stable structure of the carrier element 22.
  • the invention can also be used without a fan, that is to say in the case of passive cooling, in which there is no active generation of a cooling air flow.
  • the air 32 heated by the semiconductor light source 20 is blown in the direction of the projection lens 50, passing the aperture roller 48.
  • the light module 100 is therefore set up to guide a cooling air flow generated by a fan in such a way that the screen 48 lies at least in part in the cooling air flow 44. This provides the additional advantage that the heated cooling air absorbs moisture that can condense in the motor vehicle headlight at changing temperatures and / or air humidity and carries it out of the motor vehicle headlight with the air flow.
  • the air blown towards the projection lens 50 has the further advantage that this air sweeps past the diaphragm roller 48 and can thus dissipate heat from the diaphragm roller 48 when it has heated up.
  • Another advantage is that the blower 42 ensures temperature leveling, that is to say compensates for temperature differences within the cornering light module 100. A distortion due to different temperatures of different areas of the holding frame 22b and / or the swivel frame 28, which leads to tensioning of the bearings 30, 32, is thereby reduced. The warpage-related surface pressure between the bearing surfaces of the two bearings 30, 32 is thus also reduced.

  • the second part of the carrier element 22, ie the holding frame 22b consists of such a material.
  • the attachment of the holding frame 22b on the heat sink 22a takes place, for example, by screw connections.
  • the attachment takes place in that a section of the heat sink 22a is inserted into a plastic injection mold of the holding frame 22b and overmolded with plastic material of the holding frame 22b, so that after cooling and hardening, a connection between the heat sink 22a which can no longer be broken is non-destructively and the holding frame 22b.
  • the overmolding produces a very good thermal contact between the heat sink 22a and the holding frame 22b, which also contributes to leveling the temperature differences within the cornering light module and in particular the two bearings.
  • Both the material of the diaphragm roller and the material of the holding frame preferably consist of a highly thermally conductive plastic composite material.
  • the holding frame 22b Due to the thermal coupling of the holding frame 22b to the heat sink 22a, the holding frame 22b also takes on heat sink functions. It therefore absorbs heat from the heat sink 22a. This is due to the good heat conduction Heat also serve to heat the two bearings during operation of the light source, which advantageously reduces the effect of bearing clearance degradation at low temperatures that was described as problematic above.

  • the primary optics are focused on the small volume. This is achieved, for example, by an arrangement of an ellipsoid reflector and a light source, which is arranged in a first focal point of the reflector when the small volume is in the second focal point or focal region of the reflector.
  • the secondary optics is also focused on the small volume and projects the light distribution in the small volume into the apron of the light module.
  • a diaphragm edge 54 which is located within the small volume, is then imaged by the secondary optics as a light-dark boundary in the light distribution projected into the apron.
  • a light from the light source can also be used focusing lens or a lens with internal total reflection can be used as primary optics.
  • the diaphragm roller 48 is rotatably mounted about a horizontal axis of rotation perpendicular to the optical axis 40 and preferably parallel to an axis of rotation which runs horizontally when the light module 38 is used as intended, and has various contours on its circumference which are due to the secondary optics on the road are projected and represent different light-dark boundaries.
  • the entire length of the diaphragm roller is illuminated by the primary optics.
  • the area of the light distribution or illumination below the diaphragm edge 54 is shaded by the diaphragm roller 48 and appears as a dark area in the light distribution projected onto the street.

  • the small volume into which the primary optics focus the light has an area that is typically less than or equal to the upper half of the cross-sectional area of the diaphragm roller when a cut is made along its axis of rotation. In one example, this is an area of approximately 50 mm * 5 mm.
  • the light emerging from this small cross section is scattered into the broad light distribution on the roadway by the secondary optics, that is to say in the embodiment shown, by the projection lens 50. That means vice versa, that radiation incident from the outside via the secondary optics into the projection light module 100, ie not only visible light but also infrared radiation and ultraviolet radiation, is correspondingly strongly focused. This focusing can lead to thermal loads. Conventional plastic cannot withstand these loads under unfavorable circumstances, i.e. with high radiation levels.
